| 摘要 |
This invention presents an NOx environment effective reduction apparatus comprising a sulfur tolerant, high water vapor (about 3% to about 18%) tolerant, packing-free coronal-catalyst. In one embodiment the invention comprises an NOx reduction apparatus of high water vapor tolerant coronal-catalyst adapted and configured for hypercritical presentation of an electrical field to an NOx bearing gas stream, where the electrical field has a minimum field power density of at least about 75 watts/cubic meter, and optionally, accompanying downstream scrubbers. In a particular embodiment, downstream wet or dry absorption arrest particular NOx reduction products NO2 and HNO3, optionally upon exposure to an arresting agent, including basic, caustic, or alkali materials such as CaO or NH3.
